The Planck length=smallest thing there is.

Imagine tiny magnetic balls that size filling every crack and crevice of a space. There are voids here and there setup by the vibrations of these teeny tiny magnets, that are all vibrating and exciting each other throughout the whole of, well, infinity.

Imagine the vibration pattern as what you see in the pic below. Now, realize that the tiny magnets are in dimensions you can't see, but are all around you. The voids previously mentioned are you! They are your so-called, "atoms," that make up your body and everything else that you can see and measure.

We're a mirror of a higher-dimensional plane that is the exact opposite of us in all ways. Our space is empty, that other plane is completely filled. Our energy is positive and that other plane is negative (although from that other plane, we're the negative. ) Get it?
